I guess people are still spectacularly missing the real point.   The
point
isn't that  the latest generation hardware cpu du jour you can pick up
from
the local hardware store is doubling processing power every n months.

agreed.

The point is that getting them qualified, tested, verified, and then
deployed is a non trivial task. We need to be substantially behind
moores
observation to be economically viable. I have some small number of route
processors in my network and it is a major hassle to get even those few
upgraded. In other words, if you have a network that you can upgrade the
RPs
on every 18 months, let me know.

yow.  while i agree that routing processors cannot, and have historically
not
had to, track moore's law, i am still surprised to see such a heavy focus
on
the RP.  my (ample) gut feeling on this is that system level
(combinatorial)
effects would limit Internet routing long before moore's law could do so.



It is an easy derivative/proxy for the system level effect is all. Bandwidth
for updates (inter and intra system) are another choking point but folks
tend to be even less aware of those than cpu.
